Stair tread steel grating is one of the most widely used application of steel bar grating. It can be installed in the factories or in the parks for the permanent or temporary using.
Stair tread can be made of low carbon steel, aluminum steel and stainless steel gratings. The low carbon steel grating can be galvanized and painted for better corrosion resistance.
Types of stair tread steel grating
According to the different fabrications of stair treads grating, it can be divided into welded stair treads, press-locked stair treads, swage-locked stair treads and riveted stair treads.
Among the four types, the welded grating stair tread is the most widely used type. It has firm structure and simple technology.
The press-locked and swage-locked stair tread can supply better lateral stiffness than other types of gratings.
And the riveted stair treads features higher load carrying capacity for longer service life.

According to the fixing type, it can be divided into bolts connections and welded connections.
The bolts connection stair treads grating allows for the temporary using and easy installation and uninstallation.
The welded connection stair treads features durable and firm structures, it can be used in the permanent applications.

According to the front nosing, it can be divided into without nosing, checker plate nosing, vertical stripped plate nosing and round hole plate nosing.
Without nosing stair treads grating is available for common applications.
Different nosing type can improve the slip resistance performance of grating, it is suitable for wet or slip applications.

According to the stair tread grating surface, it can be divided into smooth or plain surface and serrated surface.
The smooth surface stair treads have even surface which is artistic and is suitable for common applications.
The serrated surface stair treads has better anti-slip performance, which can be used for special applications.
